To all whom'it ay concern;

Be it known that I, H,;H'4n'r, a citizen of, the United States, residingat New Haven, in the county got new and State of Connecticut, haveinventedva new and useful Improvement in Locks .ior

Vehicle-Doors; land I- do hereby declare the followingywhen taken in,connection with 'vention isto provide the accompanying drawin "land thechinacters of reference mark thereom toihea full, clear, and exactdescription of,the same, and which saiddrawings constitute part of thisapplication, and represent,'in,

Figure 1 front view of a lock fervehiele doors, constructed ineccordancewith my invention. I w l Fi 2. A front view, part1 broken aweshowing the handle unlocke and partial turned to expose theescutcheon-plate; g

Fig. 3. A rearview of the esonteheonplate detached. i i Fig. 4. A. topview, showing the handle in its ocked position.

This invention relates-to enimprovement in looks for vehicle doors andparticularly to locks-which-aire mounted in thedoor-hem die. In the moregeneralconstructionfof these locks, the handle is secured in place byextending the spindle through the door 7 and mounting a nut .01: otherfastemn device upon the inner end ofthe '5 mile, I his 7 the attechmare" covered so that tampered with without ops necessitates thepositioning 0 the handle before the inside-of the door is finishe' -andin case it is desired toremove the hen le, it

necessitates tearing away; the upholstery upon the inside of the'door.On the otherhand, if the lock is secnre'dinplaceby means outside of thedoor, such means are exposed so that anyone so dis eob'ect otthisinmeans o'rjsec H the the outside of the] cor,

and open the handle in place from and also to provide means forcoveringrthe. heads of the screwsvso that they cannotihe removed withoutunlocking and turning the handle; and the invention consists in theconstruction as hereinafter described and In carryin out my invention, Iemplo a handlefi 0' any approved design, forms with a shank 6 mounted.on the end ofthe usual spindle 7. The shank- 6 contains the usualpm-tumbler clinder 8 opcratedby ad with thecylinder tobe key 9, andconnecte H e a a ofa dowel pin 12-.on the handle, extending mto'e hole13;formed for itin the hub. Upon; the for1nedwi ,7 I

he secured to-the: outsideofe doorby screws which extends into "plate,the escutcheon-plate being held in placeby aloe r y in t n they can noted, can, by removing the screw? rea "1y remove the handle fsai shank,ahub oonnecte and formed with a flange, an escutcheon plate having screwholes adapted to be se- 10o "hub oonnected withthc handle,

Thiseseutcheon-plate is formed withnotches 18 into which the locking-pin,'10 may extend so as to lockthe handle with the cscutche'on- -colla.r 19or other suitable means. The hub 11 is formed with a flangefldpreferablpacorresponding in form to the escutcheon-p to 14, or atleast provided with projections 21 which will extend over ,the screweldwhen the handle is in the normal position:. As herein show-n20qisiormodwith notches 22 e fl n which; when the flen 'e is turned toexpose the screws 16, the notdhes will "give clearance space to permitits screws to be removed or inserted.

It-will thus &be seen that my improved a handle mny'besecured inposition from the outside ot-the door and connected therewith by screwsapplied from the outside, and that when the handle is in the lockedposition,

:ating the locln It is obv'iouewithout ther illustration, that the hub11 might be .formed' integral with the handle 5, 1f desired, although'itwould be a more expensive method of manufacture.

1. Alock for vehicle doors, comprising a handle including a shank, atransversely arran d keyroperated diln m e an e cured to the outer faceof the door, the flange =01) the hub iirrangedto cover the screw holesinthe escutcheon-plate when the handle is iuthe locked osition.
